Meaning of the LeD
Line LeD (yellow):
control powered
Alarm LeD (red):
machine alarm (the siren symbol on the
display is on only when the buzzer is active)
on LeD (green):
machine ON from keypad or supervisor
(referred to the EEPROM variable). The effective ON status of
the machine may, in addition, depend on the ON-OFF digital
input, on the active time band, the stand-by condition transmitted
from the master unit (if a series of units is in rotation), and is
indicated by the illumination of the fan symbol.
the on-oFF symbols on the Display are illuminated only
when the input of the remote contact is enabled and
indicate the status of such contact.
